A few weeks ago, I created a post saying how much I hate the panoramic windshield. Love the car, HATE HATE HATE the Pano Roof. I have been complaining about the panoramic windshield since the day I got my P90D. I searched all over the Internet but couldn't find one single sunshade that is easy to install/uninstall, that is usable while driving, and most importantly that blocks both heat and light. So I went on and design my own with the help of a sunshade manufacturer. I tested the sunshade on my car, Very Happy with the result. My sunshade can be used while driving or parked. Extremely easy to install, simply pat it to the windshield and it will stick. When you don't want shade, just gently peel it off the windshield. Would you be interested in getting one, if it is available on the market? Please see attached youtube video.
